Voice and Video Calls
Using WebRTC for video and voice calls
What you need
A modern machine with camera and mic. Expensive old Windows machines are not so good, and tricky to configure. Cheap new Chromebooks (less than US$200) work perfectly. Macs work out of the box.
The latest version of Chrome, Firefox or Edge.
Newer Android mobile phones and tablets (some less than US$50) will also work.
Test your device for compatibility
Use this online device compatibility verification tool to determine if your machine and browser combination is ready for video conference. Everything should pass except for IPv6 support.
Multi-users video / voice calls
This is a completely experimental implementation that stretches what web-rtc offers. Use at your own risk.
